Eh, be like our pal DSP and drink gin. It's a clear liquor and it mixes well with seltzer water and ice since it doesn't have a ton of flavor itself, so there's the fewest calories possible and no pesky congeners to make any hangovers/strain on your body more serious. Plus you can mix it with fruity shit to make drinks women and dudes with pitiful constitutions won't complain about. No surprise that drinking is about the only thing good ol' Phil does right.
But of course this is exactly why serious alcoholics like Ralph wind up in the state they are: they aren't thinking about harm reduction, they're just thinking about tossing that shit down until they're so deep in oblivion that what they're doing to their body doesn't even matter anymore.
That's the key to understanding addiction: addicts know they're killing themselves and destroying their life, and it upsets them, and the only way they know of to deal with upsetting feelings is to take more, and so the cycle continues. It's some really tragic and sick shit if I'm being honest, and in my many years of experience around addiction I have to say alcohol may overall be the worst of any.
